There is a “UnitsML” technical committee within OASIS that should be able to help you directly....

Japanese has a completely unique measuring/counting system.

 

Kimonos, whales, pens, floor mats, …but all of this requires multi-language

and cross language capability for metadata.

 

Is there a group handling Japanese/Chinese metadata and ontology systems?

 

We are build a US Government system for managing global operations with global

language domains; and including the metadata structures for handling ontologies.

 

Is there a group that is working on this?

This might be a great place to perform some ontology work which would demonstrate a huge benefit to society.  The WCO has major issues mapping to and  from various languages for UoM.  For example, in Japan, you use a completely different counting system for anything that is flat.  Even thinks in North America have vastly different units of measure.  Mapping each of these ontology concepts to terms in various languages would be a huge issue.  Think about these units of measure:

A dozen eggs
A “loaf” of bread, but also has weight
Apples are not sold each in most places but by aggregate weight
Liquids are sold by volume
Long things are often sold in lengths
Flat things are often sold in square feet or meters
Firewood is sold by volume (chords), processed timber is sold by units, square feet, length and other measures.  They all come from trees.
...

This list goes on and on.

I bet there would be funding for this type of work.

Dear Henson,

I agree with your comments, but the terminology is difficult. See:

ISO 31-0:1992 - Quantities and units - Part 0 - General principles, Clause 2.1:

"Physical quantities may be grouped together into categories of quantities
which are mutually comparable. Lengths, diameters, distances, heights,
wavelengths and so on would constitute such a category. Mutually comparable
quantities are called "quantities of the same kind."

"If a particular example of a quantity from such a category is chosen as a
reference quantity called the <em>unit</em>, then any other quantity from
this category can be expressed in terms of this unit, as a product of this
unit and a number."

>From this I deduce that:
- The length 2.3 m is a "quantity".
- Length is a "quantities of the same kind". The synonym "quantity category"
is also used implicitly used in the text.

I don't think that the ISO 31-0 terminology is ideal (I do not know whether
ISO 80000 is the same). However, it is important to have an onotology which
uses the same terminology of the standards from which it is derived. This is
why it is necessary to have ISO TC12 on board.

The second paragraph worries me - this is true for some "quantities of the
same kind", but not others. Perhaps after discussion we can define the
subclass of "quantities of the same kind" for which this is true.

Best regards,
David

p.s. I have take the liberty of cc'ing this to the ontology summit to see if
the discussion "rings any bells" with others.
